Does stimulus-independent ERP make sense/ exist?

An ERP is an Event Related Potential, making it inherently connected to an event. Having stimulus/response independent ERPs is thus impossible. There do exist potentials that seem to be stimulus ...

How do I obtain recordings of the P300 wave of the event-related potential in the EEG?

The P300 wave is a positive deflection in the human event-related potential (ERP). A common experiment in which it is analyzed is the "oddball" paradigm, where a subject detects an occasional target ...

Does stimulus-independent ERP make sense/ exist?

Resting state EEG protocols already exist, but they do not focus on ERPs (thus solving your problem). You can assess coherence between pairs of electrodes (if you enter 'resting state EEG' into google ...

What are ERP components such as N400?

The semantic N400 and syntactic P600 are some of the most well established ERP components in the literature. They were discovered decades ago and the results have been replicated hundreds of times in ...

Readiness Potential vs. Lateralized Readiness Potential in ERP

The Lateralized Readiness Potential can be considered a later component of a more generalized Readiness Potential, i.e., an LRP would develop out of an RP. As such, RPs can be interesting if you want ...

Sources on P1/N1 modulation with checkerboard probe

For the fundamentals, I always go back to the more dated literature that is heavily cited (in this field of research, which is pretty big given it uses visual evoked potentials, say >1k times). I ...

Do you know any good tutorial on designing EEG experiments with PsychoPy?

You can buy the book in particular Chapter 18: Building an EEG study. There is also the PsychoPy forum with 50+ questions about EEG. You could also go to the lead developers OSF page and steal some ...

Do you know any good tutorial on designing EEG experiments with PsychoPy?

A collection of classic EEG experiments implemented in Python and Jupyter notebooks. Currently, all experiments are implemented for the Muse EEG device and using psychopy lib for stimulus ...

What cognitively interesting event-related potentials at FP1, FP2, TP9 or TP10 can be measured with consumer-grade EEG hardware?

I don't have experience with consumer grade EEG, but at fp1 and fp2 you should be able to measure the P3a response. Given the high impedance you will need a lot of trials, but the response is ...

Can an EEG response be phase-locked but not time-locked?

When people talk about phase-locked within EEG, they mean at the same phase relative to some index time (e.g., stimulus onset). I'm having trouble imagining anything 'real' that would be phase-locked (...

What are ERP components such as N400?

Just for reference, I'm an undergrad but I'm doing an N400 study currently. As for your latter questions, since I think the former have been answered really nicely(it is kinda a harder concept, data ...

How do I interpret an effect of electrode position in ERP research?

The question is quite vague, as it is unclear what the sample size is and whether OP is talking about an anecdotal experiment or the outcome of a well-powered statistical analysis. Moreover, there is ...
